EDMUND SPRUNG HARRYHo sE longitudinally-movable in said casing By use ofa number of needle valves' together with a proper proportioning of theclosure, the carbureter may be permanently adjusted by experiment tomeet the requirements 01" any motor t'o'which it may be con:nectedthereby making it especially 'eflicient' for use in automobiles01%,the like.

-Obviously changes inthe details of-construction may be; madewithout-departing from the spirit of the invention and we do; not care"to limit ourselves'to any. particular form or arrangement of parts.
